Fox Guest Convinced ISIS Is In America: 'I Would Bet My Life' On It

A conservative filmmaker said Wednesday during an appearance on "Fox & Friends" that he's convinced ISIS is in America and that members of the jihadist group entered the country by crossing the U.S.-Mexico border.

Dennis Michael Lynch, whose work focuses on the border and illegal immigration, appeared on the show to discuss immigration.

"I would guarantee you, in fact I would bet my life on the fact -- your last guest just said about ISIS coming into America -- I would guarantee you, they're already here," Lynch said. "I have worked in the desert and I have caught these people before and I've seen Qurans, prayer rugs, you name it. They're already here."
